I recently got a transformer prime and just want to check whether the odd responses in the touchscreen are normal or not.

Below I have attached a screen shot from Photoshop touch. The odd snakeing down the diagonal strokes makes me think something is not quite right about the tablets touch screen. Is this normal on other primes?

Yes, as smooth as I can. I have also had the same results using a wacom bamboo stylus. Also the tablet was running in its "performance" mode, to ensure it wasn't CPU skips that were causing the issue.

Obviously not a scientific test, as I used my hand and not yours, but Photoshop Touch on a Xoom I get far smoother lines, with none of that odd wobblig on the big strokes.

THIS IS the ASUS answer I received! Really, sweep it under the carpet. I cannot return this unit, is already over the return period time....

I own a TF 201, I installed SketchBook Pro.

I also have an Ipad 2 (from work) with the same same software.

My issue, is the Transformer Prime, does not respond very well compare to the Ipad.

I truly wonder if this is a problem with the Transformer since all application even Skitch do not produce very smooth response be it with finger or capacitive stylus. Rendering drawings on the prime, results in broken lines, circles which are not complete and always feel like the line has to "catch up" to your finger or stylus. This is not a problem I experience on the Ipad.

Can you please advise if this is "working" as designed or is this a case of a screen not working to par (and how to resolve or exchange)? This is truly proving to be a disappointment has drawing is a very important feature to me. More so since this works flawlessly on the Ipad.

We apologize for the late response. It is only till your email sent to
Satisfaction-CA, I have picked up the case. Regarding to the problem
that you were/are having, I ams afraid ASUS will be limited to support
your product since this is a third party software, and you might have
to contact the vendor for technical support. Given the fact that iPad
and Prime are equipped with different OS, it is possible that the
experience of using a complete identical software might varies. We are
very sorry for the inconvenience induced in this matter. Please let us
know if further questions and concerns raised. Your kind understanding
is greatly appreciated.

There is a chance that this issue can be softened at an application level. (Changing the device's reported position itself would be better but not possible without changing the kernel as far as I was informed).

This is an example of some diagonal lines I've drawn myself (can't post image):

I posted this idea in forum.xda-developers.com/showthread.php?t=1516716 .
The writepad app dev said he would try this but he has been really busy so I still haven't any reports on whether this works or not.

I also have this issue and am very disappointed. I wanted an ASUS transformer Prime to replace my Motorola Xoom, but the Xoom performs much better in this respect. So in my opinion this issue is not 'normal'. It could be solved. I hope Asus will solve it with a software update. For now, I am not getting rid of my Xoom just yet...
